PROBLEM TO BE SOLVED: To provide a mole repellent device which avoids moles getting used to noise and vibration and keeps excellent repellent effect for a long period.SOLUTION: The mole repellent device 1 repelling moles includes: a square pipe 2 which is at least partly buried in the ground a weight 7 arranged inside of the square pipe 2 and a motor 11 which makes the weight 7 have irregular turning operation through a spring 8, so that the irregular noise and/or the vibration generated when the weight 7 making the irregular turning operation according to the motor drive contacts the inner face of the square pipe 2 can repel moles.COPYRIGHT: (C)2015,JPO&INPIT【課題】モグラが音や振動に慣れることを回避し、長期にわたって良好な忌避効果を維持する。【解決手段】モグラを忌避するモグラ忌避装置1であって、少なくとも一部が地中に埋められる角パイプ2と、角パイプ2内に配置される錘7と、バネ8を介して錘7を不規則に旋回動作させるモータ11とを備え、モータ駆動に応じて不規則に旋回動作する錘7が、角パイプ2の内面に接触する際に発生させる不規則な音及び/又は振動によってモグラを忌避する。【選択図】図2
